Just realized how a customer's question about marbling changed my approach
This regular asked why some steaks have more fat lines, and I had to break it down simply for her. It made me think about how I describe cuts to everyone, not just other butchers. Now I start by showing the fat content and how it cooks, which helps folks pick better. My coworkers have started doing it too, and sales on the pricier cuts have gone up a bit.
There's this bar downtown that has about twenty hot sauces on the wall. My friend always hated spicy food until the bartender just said, "Try this one, it's like a flavor hug first, then a tiny kick." That totally changed his mind.
